Babel is used by millions, so why are we running out of money? (2021)
I do appreciate your transparency, though I disagree with the sentiment that Iām arguing from a position of bad faith.
Itās a self-evident fact that the Babel team has not shown a moment of interest in lowering their role in the JavaScript ecosystem to anything short of kingmakers. Have a gander at their GitHub README and what do we see?[1]
- āBabel is a compiler for writing next generation JavaScript.ā Indefinitely.
- Over a dozen sponsor logos. An embarrassment of riches.
- A literal audio recording of a song in praise of the project.
The Babel team has a well documented history of their priorities[2], emphasizing the need for a modular approach that has no exit strategy[3]. At best, we have a case of accidental entrenchment and long term dependence on the Babel brewing as early as 2017![4]
Compare this infinite circus to the humble but popular Normalize.css, which has the express purpose to stop existing.[5]
If the Babel team wants to raise some money, they can start by putting a plan together that would codify an exit strategy. Itās certainly more noble than their current plan of barnacling on to every NPM packageā¦

Reveddit does not work
The problem was I had used some new code, Javascript's replaceAll(), that is unsupported by older browsers. And, the setup I have to automatically fix such issues (called babel) is out of date. So, while this problem appears to be resolved there, I hadn't updated that in awhile.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: ā¢ If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. ā¢ If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript ā¢ To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. ā¢ If you need a custom transformation specify a "transform" option in your config. ā¢ If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
